2. A type of swimming goggles with step-less adjustment comprising:
two lens frames each receiving a lens, each of said lens frames including a first joining unit located at an inside edge of said lens frame, and a second joining unit located on an outside edge of said lens frame, and each of two lens frames having a clasp piece extending along an upper rim and a lower rim of each lens frame to form fixing grooves, at least one string, said string passing through said first and second joining units of said two lens frames and being secured in said clasp pieces of said two lens frames so as to maintain a desired separation distance between said two lens frames, said string extending past said lens frames so that ends of said string are exposed, and a headband device joined to said second joining units, said headband device comprising at least a headband; wherein each said first joining unit includes two through holes, and each said second joining unit including two engaging holes with clasp openings; and wherein said at least one string has a diameter less than the diameters of the through holes and the engaging holes to facilitate easier adjustment of said at least one the string.
1. A type of swimming goggles with step-less adjustment comprising:
two lens frames that each receive a lens, each of said lens frames including a first joining unit located at an inside edge of said corresponding lens frame, and a second joining unit located on an outside edge of said corresponding lens frame, and each of said two lens frames having a clasp piece extending along an upper rim and a lower rim of each lens frame to form fixing grooves, a first string passing through said second joining unit of one of said lens frames, along the upper rim of said one of said lens frames and being secured in said corresponding clasp piece, through said first joining units, along the upper rim of the other of said lens frames and being secured in said corresponding clasp piece, and through said second joining unit of said other of said lens frames so as to maintain a desired separation distance between said two lens frames, said first string extending past said lens frames so that ends of said first string are exposed, a second string passing through said second joining unit of said one of said lens frames, along the lower rim of said one of said lens frames and being secured in said clasp piece, through said first joining units, along the lower rim of said other of said lens frames and being secured in said corresponding clasp piece, and through said second joining unit of said other of said lens frames so as to maintain a desired separation distance between said two lens frames, said each string extending past said lens frames so that ends of said second string are exposed, and a headband device joined to said second joining units, said headband device comprising at least a headband; wherein each said first joining unit includes two through holes, and each said second joining unit includes two engaging holes with clasp openings; and wherein each string has a diameter less than the diameters of the through holes and the engaging holes to facilitate easier adjustment of the strings.

This application is a continuation-in-part application of the application Ser. No. 09/541,223 filed on Apr. 3, 2000, now U.S. Pat. No. 6,349,417.
Field of the invention
However, one drawback of the aforementioned parent application design is that the diameter of the clasp openings 501, 511 is 2 mm while the diameter of the strings 60, 61 is also 2 mm, and this tight engagement therebetween will make it inconvenient for the user to adjust the nose bridge. Another drawback is the strings 60, 61 is tightly clipped by the clasp pieces 502, 512, and thus it is difficult to separate the strings 60, 61 from the clasp pieces 502, 512.
The primary objective of the subject invention is to improve the inner side of the lens frame so as to have the string adapted to move smoothly through the clasp piece. Thus, it is easy to adjust the span while the span will not be affected once adjusted.
The subject a pair of swimming goggles with step-less adjustment includes a pair of lens frames having first and second joining units at two opposite ends of each lens frame. The first joining unit located on the inner side of the lens frame, has two through holes, and the second joining unit located on the outer side of the lens frame has two engaging holes each with a clasp opening communicatively aside. The diameter of the through hole corresponds to the diameter of the engaging hole. The strings connect the pair of lens frame. The diameter of the string is smaller than those of the through hole and the engaging hole. The end of the string could smoothly passes through the through hole of the first joining unit, and the end portion of the string is successively received in the engaging hole via the clasp opening. When the user would like to adjust the distance of the nose bridge, he may only separate the end of the string from the clasp opening, adjust by moving the string to obtain a proper distance to meet the required nose bridge, and finally re-install the end portion of the string into the engaging hole.
As shown in
The strings 20, 20' are made of flexible material. The diameter of the strings 20, 20' is 1.9 mm which is smaller than that of the through holes 1011, 1011' of the first joining units 101, 101', and also smaller than that of the engaging holes 1020, 1020'. Thus, the strings 20, 20' may smoothly pass through the corresponding through holes 1011, 1011' and the engaging holes 1020, 1020'. Therefore, it is more easily to adjust the dimension of the nose bridge by moving the strings 20, 20'. The protective pads 30, 30' are respectively assembled into the lens frame units 10, 10'. The protective pads 30, 30' have face contact parts 301, 301' with flexibility thereof to allow comfortable contact with the user's face.
